They've gotta be feeling the pain at this point. With the Tamron and Sigma lineups, many of the core lenses everyone buys (18-35 APS-C, 24-70, 70-200, 35, etc.) are as good if not better from 3rd parties. It has to be taking a toll on sales. In this particular case, everyone who needed a better 35mm F1.4 already has or will have the Sigma by the time this mk2 comes out. The remaining mk1 owners that didn't upgrade will have a choice of the Sigma for $900 or the mk2 likely for $2200 minimum $1800? And barring some massively revolutionary engineering break through, it will only be as-good as the Sigma, not better.
I wouldn't be surprised to see changes from Canikon soon, as far as technology lock-down. It's the only way they're going to maintain profit margins. "Foreign Lens Detected, disabling feature XXXX".
